【摘要】：为深入细致分析陕西高技术产业的效率,采用两阶段DEA模型分别计量分析其知识创造效率与知识利用效率。结果表明,陕西高技术产业的知识创造效率和知识利用效率处于双低状态。导致这样状态的原因有,首先是占陕西省高技术产业总量接近1/3的航空航天设备制造属于国家战略性产业,它在市场上很难完全反映出来。其次是陕西高技术产业的最小有效规模较高,这使陕西高技术企业的现实规模仍处于偏小的不合理规模上。而在知识创造阶段,RD的相对投入不足不仅导致其产出数量不足和质量偏低,这又进一步影响其知识利用阶段低效率。最后,陕西高技术产业内部市场交易不活跃、分工协作水平低和一般市场化程度低是导致其效率双低的重要外部根源。
[Abstract]:In order to analyze the efficiency of Shaanxi high-tech industry in depth and in detail, two-stage DEA model is used to measure and analyze the efficiency of knowledge creation and knowledge utilization respectively. The results show that the knowledge creation efficiency and knowledge utilization efficiency of Shaanxi high-tech industry are in a double low state. The reasons for this state are as follows: firstly, the manufacturing of aerospace equipment, which accounts for nearly 1 / 3 of the total high-tech industry in Shaanxi Province, belongs to the national strategic industry, which is difficult to be fully reflected in the market. Secondly, the minimum effective scale of Shaanxi high-tech industry is higher, which makes the actual scale of Shaanxi high-tech enterprises still on the small unreasonable scale. In the stage of knowledge creation, the insufficient relative input of RD not only leads to the shortage of output quantity and low quality, but also affects the low efficiency of knowledge utilization stage. Finally, the internal market transactions of Shaanxi high-tech industry are not active, the low level of division of labor and cooperation and the low degree of general marketization are the important external causes leading to the double low efficiency of Shaanxi high-tech industry.
